Question

At another school they sell a different brand of gift wrap which costs $2 per package and cards for $5 per package. Your friends class sells 220 packages and earns a total of $695. Find the number of each type of package sold

(using systems of equations)

Answer 1

Hi there,

5x?=110 ?=22

how? 110/5=22

now 2x?=110

110/2=55 ?=55'

so we know now that people bought 22 packages with card and 55 w/th out cards!

so no we need to divide 695/both

695/5=139 packages with cards

695/2=347 packages without cards

SO

139 packages with card

347 packages without card
